[Healeys] Voltage regulator query

[Alex]

About two years ago I replaced the original voltage regulator on my BT7.

The replacement, made in India, worked okay, but recently I have had to 
burnish the contacts on the main coil in order to get it to provide a 
charge.

I have been thinking about refurbishing the rugged original Lucas 
regulator. Its resistor is fine and the coils do not look overheated or 
discolored.

Are there any suggestions about finding a rugged voltage regulator these 
days?
